In my opinion, the answer is 'yes'. Generally speaking.
Heavier bows = more stable bows, just as longer limbs = more stable bows.
The argument for proper bow design is a seperate issue. A heavy riser longbow and a 'properly' designed longbow are not necessarily mutually exclusive if more mass is your preference.
That said, bows like the Bob Lee stick and Fedora excelerator have larger risers as do several 3 piece take downs with recurve like risers.
Acadian Woods, Brackenbury and again Bob Lee for TD's
I'm still diggin my Dwyers and with 68" limbs and a BOA quiver they are stable, smooth and quiet as can be.
